#### Mifflin equation

## What is the Mifflin St JEOR formula?

Nowadays, the Mifflin-St Jeor equation is believed to give the most accurate result and, is therefore what we used in this calculator. This BMR formula is as follows: BMR (kcal / day) = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (y) + s (kcal / day) , where s is +5 for males and -161 for females.

## How accurate is Mifflin St JEOR equation?

Of these equations, the Mifflin-St Jeor equation was the most reliable, predicting RMR within 10% of measured in more nonobese and obese individuals than any other equation, and it also had the narrowest error range.

## What is the formula to calculate BMR?

There are 2 formulae used to calculate BMR, in [kcal / 24hrs] for men and women respectively:BMR for Men = 66.47 + (13.75 * weight [kg]) + (5.003 * size [cm]) − (6.755 * age [years])BMR for Women = 655.1 + (9.563 * weight [kg]) + (1.85 * size [cm]) − (4.676 * age [years])

## What is the unit of BMR?

Basal metabolic rate (BMR) is the rate of energy expenditure per unit time by endothermic animals at rest. It is reported in energy units per unit time ranging from watt (joule/second) to ml O_{2}/min or joule per hour per kg body mass J/(h·kg).

## What is a good BMR?

What is my average BMR? Most men have a BMR of about 1,600 to 1,800 kCals a day. Most women have a BMR of 1,550 kCals a day.

## At what age do women’s metabolism slow down?

You’ve probably heard that once you hit 40, it’s all downhill when it comes to your weight. That inexplicable force we call our metabolism does begin to grind a bit slower every year from age 30 onward.

## How do you calculate tee?

It is calculated by adding 30% of the Basal Energy Expenditure (BEE) calories to the BEE for sedentary activity. 50% of the BEE calories for moderate activity and 100% of the calories for strenous activity.

## Whats is RMR?

Your resting metabolic rate (RMR) is the amount of energy (calories) your body burns while at rest. It is one of three components of your total metabolic rate, comprising of 70 percent of your body’s daily energy expenditure, Boyd says. The RMR test is a simple, non-invasive test that determines your RMR.

## How do you calculate your BMI?

Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m^{2} where kg is a person’s weight in kilograms and m^{2} is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.

## How do you calculate ideal body weight?

Ideal body weight is computed in men as 50 + (0.91 × [height in centimeters − 152.4]) and in women as 45.5 + (0.91 × [height in centimeters − 152.4]). A simple alternative would be to compute ideal body weight as the weight corresponding to an ideal body mass index of 22 kg/m^{2}.

## Do you really have to burn 3500 calories to lose a pound?

Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, it’s estimated that you need to burn about 3,500 calories to lose 1 pound. So, in general, if you cut about 500 to 1,000 calories a day from your typical diet, you’d lose about 1 to 2 pounds a week.

## Is low BMR good?

A low BMR means you have to eat less calories in order to lose body fat and weight. The Metabolic age is calculated by comparing your Basal Metabolic Rate to the average BMR of your chronological age group. If your metabolic age is higher than your actual age, it’s an sign that you need to improve your metabolic rate.

## What is the lowest BMR possible?

The lowest sleeping metabolic rate (measured for 60 min) has been reported to be 88% of BMR (Goldberg et al, 1988). They also reported that overnight energy expenditure measured over 8.5h was 95% of BMR in the same subjects (Goldberg et al, 1988).
